`fish` is a command-line shell written mainly with interactive use in mind. The full manual is available <a href='index.html'>in HTML</a> by using the <a href='#help'>help</a> command from inside fish.
The following options are available:
-`-c` or `--command=COMMANDS` evaluate the specified commands instead of reading from the commandline
-`-C` or `--init-command=COMMANDS` evaluate the specified commands after reading the configuration, before running the command specified by `-c` or reading interactive input
-`-d` or `--debug-level=DEBUG_LEVEL` specify the verbosity level of fish. A higher number means higher verbosity. The default level is 1.
-`-i` or `--interactive` specify that fish is to run in interactive mode
-`-l` or `--login` specify that fish is to run as a login shell
-`-n` or `--no-execute` do not execute any commands, only perform syntax checking
-`-p` or `--profile=PROFILE_FILE` when fish exits, output timing information on all executed commands to the specified file
-`-v` or `--version` display version and exit
-`-D` or `--debug-stack-frames=DEBUG_LEVEL` specify how many stack frames to display when debug messages are written. The default is zero. A value of 3 or 4 is usually sufficient to gain insight into how a given debug call was reached but you can specify a value up to 128.
-`-f` or `--features=FEATURES` enables one or more feature flags (separated by a comma). These are how fish stages changes that might break scripts.
The fish exit status is generally the exit status of the last foreground command. If fish is exiting because of a parse error, the exit status is 127.
